Answer:
Facilitated diffusion in a cell has a limited amount of carrier and channel proteins, wherein if all are being used or saturated, can't transport the substances outside in to the cell, leading to the plateau of the substance.
Explanation:
In <u>low concentrations</u> of the substance outside the cell, <u>facilitated diffusion behaves like simple diffusion</u>, carriers and channels are not all used up. But in instances of <u>high concentration of the substance</u> outside the cell, <u>all the carrier and channel proteins are occupied</u> with the said substance. So <u>even if we increase the concentration of the substance, it will not increase the rate of diffusion.</u>
